About
Hi, I’m Katrien. I’m a bookkeeper, business analyst, wife, and mom. I’ve always loved structure and numbers, but for me, the real joy isn't just balancing books, it’s bringing calm and order to the chaos behind the scenes.
I’ve always naturally connected with therapists, coaches, and health professionals. Through my own life experiences, I’ve learned that we only get one life, and we shouldn't settle for "just okay" or follow a path just because it’s expected of us.
​
​The professionals who changed my life, the ones who helped me heal, grow, and see things differently, are amazing at what they do. But I noticed that behind many successful practices, the owner is quietly carrying a lot alone.
The business side feels heavy. The numbers feel stressful. There’s pressure to hold everything together while still showing up fully for clients and patients. Many of them were never taught how to run a business. They simply followed a passion for helping people.
​
​​That's where I come in.
I see my support with Second Banana as more than just bookkeeping or compliance; it’s about creating stability for people who carry a lot of responsibility. I want to give you the space and freedom to explore how you can best help others, without being chained to your desk by paperwork.
When you realize I have your back and the "business side" is under control, you finally have the space to breathe, dream big, and focus on the work you were truly meant to do.
​
After all, that is exactly what it means to be a Second Banana: being the steady support in the background so you can shine in your leading role.
